no
fr?
you don't
11th
bruh aint nobody deriving sum of angles for sine during a math comp
@glad flame Do you have a rebuttal?
but wont that take time
π
gng when did this become a debate competition
π
but it is
but it is
usually
i learned it when i was whatever age i am now
alr ig
huh?
no like it was in my syllabus
fah
when did u learn calculus?
like what counts as calculus
idk like finding area under graph
or finding type- min/max point
no like in exam dawg
uhh like integrals and riemann sums?
u told to derive in exam
yea
u learnt it when u were 15 damn
im not 15 yet
uhh
not math comps right
yea
but thats
like
wait which one did u go to
even though my friends call me that
i only went to 2 actual mo
huh
u started u sub?
orz
but y would u derive it
in the exam
wait depends on which one
what did u derive
because you cant remember everything

i asked a question
wha
g is cool
g is geometry?
nah nt sucks, I hate number theory more than I do with geo
What
combinatorics
oohh

yeah true
except fe
why sir
ew
combi and geometry are both hell
combi is worse
those shapes give me ocd even tho i dont have ocd
that's understandable
so much casework
fah

that does make sense ig
is this the chad way
im suffering with it
the ones with calculus and geo esp
am i wrong
well if you refer to AMC problems then yeah, many of them
What about combinatorial game
welll
those dont count
those count as
t=turbo the snail problems
bro......................... it is in my books
t>n>a>g>c
yes it is, majority taking calculus, cuz Asians are majority lol
this is also my point
our school needed a test to get in
that's why I asked for data
so we all asian
im asian
fahh
well i am
see
I'm so so disagree, c >>>>>> n,a,g,t
G > N >> A >>> C
close enough
nahhhh
how aare you in love with combi
how are people in love with combi
ikr
it's actually the only topic I willing to study
2022 C6 is nice though
it can be considered a troll
i'd rather do a page of calculus questions than one combi question
wha shortlist?
isl
huh
imo sl
cuz it's fun, also it has a lot of reasons and not just some computing and algebra
geom is more fun
it's me, well my alt
mhm

oh what
im sure the entire diaspora of this server would be asian
yall should glaze n more π
yeah I have like 4 alts here
as long as the question won't get overcomplicated π
ig
does anyone listen to music and solve questions?
no
yes
nahhh, as long as it does not require complex algebra
wt if it is calc BC
as long as its games or something not counting and probability its ok
no cases tho
counting is fun lol
stats sucks even tho im taking econ major
by the time i learn that in school i prolly will depend on music for my mental health
who tf enjoys stats
unless you divide it into 999 conditions
how old r u?
real
There's always some ways you can solve a counting problem w/o doing casework, or at least avoid as much as possible
uhh <15 as i said be4
that's the beauti of it
wat if
there just wasnt casework
or very little
no matter what
(everything else thats not combi)

idk, I have study combinatorics for 2 years now and I still find myself stupid, idk if I can teach anything
me but with geom

i love it when you can put graph into geometry questions π π
graph theory i think
π
like umm idk what do i call in english (im suck)
i sincerely don't think so
what language do you speak
oh jezz, graph theory getting complicated so fast, I have not got used to it
but u dont call coords 'graph'
its fun
true
graph theory best combi
oh i meant stereometry lol
just counting for god shake, it's what everyone can do and cannot do at the same time haha
raw stereometry is pure hell but putting 3d coordination making it wayyyyy easier
wat if i just cant do counting
if you can
wats a finger
@glad flame ur goated
2, 3, 1

1, 6, 7
well then you ain't do any counting ig
what if i count in base 2
sure
also n>>>>
67
stay away from it
π
AHHH GET TI AWAY
it hurts my eyes
fr
and my mental health
you all are overreacting
did you do isl 2022 c6 yet @pliant snow
its a good combi
its easy, very easy for a c6
I don't remember it
ah
Imma search it up wait
of course the problem itself has difficulty
bleurgh
i don't think I do, okay Imma try it later

nahh, only -1 and 1 sastify
ok
You might be surprised by how elegant the solution is
It's only like half a page long iirc
o wow
Is it just 3D geo w/o coordinate, like the way we do euclidean geo
ye
@fringe prism hi simp
hi freshman simp when ur a sophomore
hi freshman gooner
Hi Kyra simp
<@&268886789983436800>
Keep it SFW.
hehehehe
hmm
There is no spring break
<@&268886789983436800>
This is an on topic channel, believe it or not, please don't use the embed privs here to post off topic images, take that to #chill
hmmm
hmmmmm

yeah it's a national olympiad problem, I couldn't find the solution elsewhere
surprisingly easy for a olympiad problem ngl
wabbufet
bruh cant be that bad
Yes
itβs not
Stop this or else ive to ping mods
Off topic. Now stop
stop what
<@&268886789983436800> off topic/spam
?
bruh what
hmm
Hello friend
shut the fuck up
i do not think that was a necessary ping
ts unnecessary bro why ping?
FR
fr
hello friend
hi
hru friend?
fine hbu
good. ty gor asking friend
ur welcome friend
hi
hmm
hallo
riveting conversation
hi!
henlow
π§
I was about to ask you for the way you solved it, but I saw you sent this lol. Thank you! Interesting problem
LOLLLLLL
zelix is epic
ur epic
zelix=orz=humble
@fringe prism how does it feel to have so many pets glazing your ahh
ook
ook
woah guys calm down 
so humblee
π
dw bro ur gonna be a billionaire soon cuz of all the orz
brokillionare
na
wow how much did ts guy scroll up
he was just giving a reconsidered answer to your question 
it aint that deep really
was that an insult 
uhh what's going on
that was so yesterday
15*
Anyone know if the phods server is back up
nop
huh?
sybau gng π₯
stfu bruh
noone gives a shi which topic it is
ew is crzy
pack it up buddy
why are we lashing out
not too late to delete btw π₯
the channel has been so off topic before tho
karen of discord
gng did the mods just get pinged for no reason
Yall chill I just asked if the phods server was back up π
idk what happened
literal infant crying to mods
not ur fault
yea bad moment ig
ok the tone is a little out of line but the sentiment is right, this channel is not specifically focused on maths
oh
dont diss zelix
this isn't discussion
objection maam
actually your correct
fah
i lowk just wanted to ragebait the karen a bit
ok js move on now
mhm
yuh yuh
is anyone doing ctmc
move on timeee
gg
i want to
i'm sry for your trouble orzlord
but dont i have to go to waterloo
hell no bro im not near
yea then u dont have to
i aint driving three hours for ts
does your school have a team
ill consider it
not sure
they still havent given back our pascal results yet
dam
that was a long time ago
did u get urs back
uhh lets say i didnt
its too bad to tell anyone
u didnt do?
go dms i dont judge
nah bro
hmmm
miku enjoyer
chill
So if i murder someone a year ago, im not guilty
bit extreme no?
yea
ok ill stop

Could you stop the gif spam, please?
sorry mr. discord mod
ill take it to dms
hmmm
lmao
You've been warned repeatedly about gif spam by multiple moderators, but haven't yet faced any consequences, so here are some consequences.
Gg.
tuff
oof
was that birdy
what was the consequence
It was Birdy, as a general rule about privacy, we don't disclose details about exact punishments given, they're still in the server, so you can DM them and if they want they can share it with you.
Please don't repeat racist memes here. Only warning.
wait
whapwhat did i do
huh
wait i didnt say anything racistπ
i forgot what i said lowk
wtv
I'll DM it
rip @fringe prism
hi @vagrant dragon
o
hmm
dont get banned from here like u did from gd server
huh
all because I said hi
Thx for keeping this server clean

when was the last modping in this channel π
@trim bone 
LOL
<@&268886789983436800>
gg
least sus facebook link
real lol
like d1-2 on mods scale
it is completely trivial when you think about it graphically
ie ||represent (a_n) by colouring in [n-1, n] x [0, a_n] for each n, then when you flip it about the line y=x you get the graphic representation for (b_n)||
π₯Ά
i did it using well ordering principle but that also pretty cool
what would you rate it
prolly similar to yours (d2)
does any1 know good resources for bmo 1,2 or tmua
hmm
Thereβs some bmo here
But ask mods
Thereβs a lot of bmo there
<@&268886789983436800>
mmm
lots
hi zelix
oh.. didn't know that was a role. sadly i can't no life all day so... rah
Ur active now
Yeah ik Iβve been active for a bit but just didnβt know there was one above xd
Hi
The precise criteria for the activity roles are deliberately kept secret, in an attempt not to encourage gaming the system.
@fringe prism
oh SH
hi

hmm
What type of function is defined with its inverse? Is there a search term I can use to figure out how to solve it?
s(t) = c + .25t + s^-1(.75t-c)
In mathematics, a bijection, bijective function, or one-to-one correspondence is a function between two sets such that each element of the second set (the codomain) is the image of exactly one element of the first set (the domain). Equivalently, a bijection is a relation between two sets such that each element of either set is paired with exactl...
or u can search up inverse function
Yeah I looked up rules for inverse functions and couldn't find anything about solving this kind of equation
oh you just want it solved
well this is called
inverse functional equation i think
i didnt see the f^(-1) in the equaiton at first
I don't think there's any good general procedure for such functional equations.
i would just guess it tbh
In order to get something of a handle on it, I think I'd rewrite the equation to
s(t) - c - .25t = s^-1(.75t-c)
s(s(t) - c - .25t) = .75t - c
and then I'd guess that s might be a linear function (since the RHS is linear, and the LHS would be linear too even though s is applied twice there), so I'd set s(t)=at+b, expand , and try to solve for the coefficients a and b.
... which yields two different possibilities for s. They won't be the only solutions, though. They might be the only smooth solutions.
ye
What this channel is about?
How is it different from regular math?
π€
Search up international math Olympiad past problems for some easy problems related to competition math
For exampl
Is it any related to usamo?
I recommend doing the problem 3 or 6 international math Olympiad
They are the easiest problems to do
If you want it to be related yes
Indeed
Hmm, so it covers a wide range of concepts
what the phuck are we talking about
no, it's very narrow
olympiad math is not very broad in what it covers
it has a very narrow amount of topics it covers, but goes very deep in what it does cover
(im being serious this time)
idk if this sarcasm or what
Man I wonder
Is it?
breh
LOL
comp math is actually comp mathing π₯Ή
~~ No, too easy ~~
Prove the collatz conjecture instead

hello friend
Nah, millenium problems are easier. If you don't prove the reimann hypothesis, i will be dissappointed
Slmeone rryna look at ts book Iβm doing for amc prep
Idk if ts is a waste of time and I should be doing aops vol 1 and 2 instead
which one?
I think vol 1 and 2 are way better than any other prep books and cover pretty much a lot of topics too.
It on this site called omega learn
The dude that made it is minda cracked at math and stuff
I see
If you have time to look at the book Iβm referring to lmk if this statement is true
Cuz then Iβll switch
is it the mastering amc 8/10/12 one?
o i like that book
is it the online one
Yeah
ok, so I've done this book and it was mostly helpful for the amc 10.
it basically covers all of advanced topics needed
so ye, couldn't hurt
What abt aime
I see
Cuz Iβm noy tryna do good on amc and then js crash and burn at aime
Your loke thr all knowing do you think i should continue this book or gonto aops vol 1 and 2
do both
Iβm genuinely am locking in
if u feel like it
yeah I think it might help with aime too
Iβve started ts book do I js finish it
I see
physics related i'm guessing?
Yeah
Wait
So are we thinking that the mastering amc 10/12 book and aops vol 2 is enough for aime qual
And maybe to do good on aime?
I prolly need more stuff for this
well more skills to solve problems def means a higher chance to get into aime
but nothing is rly guaranteed
My goal is to get like the first 15-16 quesyions
And see if i can get some more afyer
Typically when i do practice tests i get around 14-15/15 and then like maybe 2-3 more in quesyions afyer those
The 2026 MA4G competition is NOW OPEN and will close on April 26, 2026.
https://www.mathandai4girls.org/
Iβm part of this program called Math and AI 4 Girls, and weβre hosting a FREE competition for girls in 8th grade or below. You can win up to $1000 in cash, plus awards and recognition! It includes some math/AI problems and short essays, and itβs not timedβyou can work on it anytime before April 26.
To foster and support a love of math, AI, STEM and sciences among middle and high school girls everywhere. It provides access to information and resources collected through a journey navigating the world of STEM. Specific information include math competitions, camps, games and gender research
hmmm
real
You love ts word dont you
Bro youve been locked
This is the 4th server i'm in that is advertising this (not including the MA4G server) π
bro i flipping hate French
Nah i believe you did good
I'll be dissapointed if you dont mop (jk)
hmmm
ill be too
hi zelix=orz
Hallo future IMO gold medalist
in real life too
When do you guy think Evan chens egmo books will come in handy
Like when do I read those
After aime?
proof writing just comes with time
just learn basic proof writing tbh
contradiction, induction, contrapositive mostly
hmmmm
egmo is the best book for olympiad euclidean geometry anyways
because you are
in general for olympiad math (different than undergraduate math just in case u want to pursue math in undergrad it is different from olympiad in many ways)
algebra: worst thing ever dont indulge
geometry: egmo
combi: something idk
number theory: monts
algebra isn't that bad
the issue is that algebra isnt even algebra a lot of times
hmmm
iykyk
anything not combi, nt, geo, they sjut throw in alg
like the
"other: " on forms
ye
Whatβs monts
I also heard ts Evan chen thing called otis
No clue what that is
if u wanna pay then go ahead
i still hold the belief u do not need to pay a single dollar to be good at maths
im sure you could do fine just using wikipedia and aops but textbooks are just better at having all the information in one place
modern olympiad number theory
(Which i can link here because it is in the public domain)
in case mods see: https://www.academia.edu/44512122/Modern_Olympiad_Number_Theory
not piracy
hmmmmm
if u want other resources i have a ton of oly resources
idk misclick prolly
you do?
yes
i hope youre being serious 
i have like 0.2TB of math
i need some resources because ive exhausted most of those online

mb
<@&268886789983436800>
I dmed
wait is this for imo only or is comc allowed
i think otis is the class he teaches or something
Any math contest can be discussed here.
alr
hmmm
Boths
quick question, do you guys enjoy doing contest math? like do you feel good after solving a difficult problem? i'm not the only one, right?
I'd say that most people are happy after solving a difficult and/or satisfying question 
ok, thats what i thought lol
nopeee that should be this whole server tbh
It feels like a great achievement
The best feeling is thinking for a long time and then one braincell creates a genius idea
Hmmm
guys im doing MAA AMC online how do i check which test centre i can go to
bro why are you spamming this everywhere
for anyone who's interested in my number theory handout (feedback appreciated!!)
unfinished, still have to finish the excercises part
interesting
although you could elaborate further on each of the theorums and points
I like the syle and format
I'll probably redo some sections and explain a couple of things better, like Euler's Theorem. I tried to keep some bits a bit shallow to save myself some time and keep it short like intended
Ty I took some inspiration from Evan Chen's CRT handout
hehe i knew it
If you dont mind i wanna see the finished product
it would be very helpful for me
once your done ofc
I'll publish it on AOPS some day, I haven't worked on it for weeks, though
Will get it done by June tho (hopefully), going to use it in my motivation letter for participating in the EMC
Romanian 7th and 8th grade tie-breaker for the International Junior Mathematics Olympiad
U got a translation?
hmmm
anyone here british and has experience with bmos?
Well check your local uni reitu
University
Most big universities tend to host just email math department or something
i took mines at an afterschool center near me
cost some money but yeah pretty simple, paid online then showed up with my stuff and tested
How do I get started on research for math Iβve tried emailing some professors but they all rejected me
maybe graduate students could help?
ummm not really
icl haven't looked into math research much yet
so many ppl cheat on amc 10 its crazy
ts is every maa contest basically
Fill in 1 digit number in boxes to complete the equation
Left to right or right to left
??
are you insinuating that shes cheating
noo?
just pointing it out for her
Shes a grade nine who does calculus she dont need to cheat
is it addition? This is not clear at all
Addition
^
hmmm
whyd you phrase it like that π
sorry bru i didnt think of it from that perspective
Okay
youre fine lmfao idk im sorry
wild, no one cheated when i took amc π
so many ppl cheat its crazy
they buy answers off the web from ppl in china who did it the previous day
the cutoffs got higher too
just curious how much time yall spend doing math everyday?
Abiut 1-2 hiurs during school days
Weekends as much as I want or havr tjme for
like an hour on school days
on weekends depending on availablility few hours
(also depending motivation)
for example today rn is my math block, just started studying
around 2 hrs
at lunch i sometimes solve problems
alr ill try ts now
tuff profile pic
ok done
@spark scaffold ts was too easy
18 must be 9+9
and then everything else is just there
its not war thnder
ook
Around 4 hours or sometimes more daily, but that is sometimes to think on just one problem (I am a super slow thinker), doesnβt mean I am oh so productive π
lol
that feeling is tha best
zoning out on a single problem for half an hour
Itβs not IMO level at all. Iβve been doing BAMO problems (just search up past papers) and just because I am such a slow thinker and my focus sometimes shifts on proving even the formulas I use, it takes me a while
ahh those
Yep, theyβre super fun
i hate them
there are too many words
but for intelligent ppl like you, maybe it will be fun
images are better
is it this? googled a problem set
True
ive lwk been having bare motivation lately
But like no time
some days ill study like 2 hrs but if i alr did like 4 hrs of hw im doing like 10 mins and crashing
hmmm
yes the 2026 one
i might do this tmrw
ah
holy
max for me is 3 hrs then i tap out
Bro how much hw you get
unless im interested
i procrastinate too much
Me too
lmao
comp sci + math (math an hour or so) + reading for ELA + chinese writing work + bio lab work
chinese yaey
the only class that doesn't give me homework is pe π₯
Holy frap
i got a ton ill show u
but its like extra stuff i find to do
I have like no cs woro
its like performance task stuff
Im fone mu Ap create task so Iβm js sitting in class
nice
I donβt do my math unless Iβm bored
I do too
π
Iβm js procrastinating on it
french, science, and math combined
hmmmmm
i do NOT wanna graph limacons and flowers fahhh
oh damn
js ask desmos
i mean igs its easy but
very
ikik im gonna for those
and the other half of the questions are "whats the equation of this flower" type
tf u mean flower
<@&268886789983436800>
<@&268886789983436800>
ermmm sorta
polar graph is like based on (x, y) turns into (radius, angle)
heres limacons, the other thing we're learning
ye i kinda forgor i wrote this
mm ic
ts like uni level stuff
like discrete math course
bro arent you in hs evelyn
Orz
orz
ye
this is in my precal course tho
maybe AP just covers more in depth than your curicullum?
ap explains a lot
this is like a video in ap classroom from college board
oh yeah also we're learning cardoids. so thats the more advanced part of the lesson
igs idk
Those can be helpful for math compe
i'm sad i can't go to precalc in 8th
also plens whats your ethnicity
9th then? meh its alr u have time or if ur school aint bitchy about it like mine js skip ab
asian
ook
same
hmmmmmmmm
chinese?
ye
same lmao
ye
ζεζ¬’ζ°ε¦οΌδΈεζ¬’ζ°ε¦θεΈγγγ
hmmm
why tho
some r very good
depends on your luck
same, so i'll just pass the aps during the summer.
like in addition to a "take home practice ap exam"
extra practice
my counslor WONT FUCKING LISTEN
we also have in person mock aps on the exam
i've asked her like 5 times atp
and then review every day until the end of the month
maybe he thinks your eccentric
she
π no placement tests or anything?
oh
my counselor also doesnt like me
sameeeee. and its sooo annoying. the school board is like, the maximum we can allow is the accelarated program. bro i did it in 3-4 grade π
i need to talk to my counseler abt the aps over the summer
Prob cuz yall r elite math geekers
she wanted to put me in the non honors "advanced 9th grade class"
and she isn't listening
like the extremist side
i touch grass
Do you need to take their counsel?
how do i check if it has it
ummm
debatable
maybe js google like amc10 testing centers
trust
ask the hs teachers, trust. they are prolly more prone to listening
my math teacher doesn't rly know either
and the math dept won't listen either
Teach just want they pay bruu
my math teacher called my counselor and argued with her and thats how i ended up here
they said that there's "no current test to skip Algebra ii"
w teacher
at least you have a math dpt
hmmm
algebra 2 is so american
our school system had a math dept... until i started 6th grade
wtf happened to it
i mean we dont have dept really its just made up of the teachers
they downgraded the lead, and the lead was the one person that let me self study calc during class
i am in america
o
state?
cali
π
atp js self study
fr
same
What are u self studying
Nice
wbu?
